Since I'm a member of the replaced rear end club, I'll weigh in here.
But first....I think you guys need to just ignore jimb's comments. I think the dude is suffering from some kinda paranoia something-or-another. You would think that anybody that is so skeptical of stuff that is posted on the internet would just stay off of the internet. Be that as it may.....
My saga of having my entire rear end replaced is chronicled on this forum. In a nutshell, with 12K miles on my truck and having towed my 2500 lb boat only 3 times, the rear end starting making a whining sound. Service writer drove it and said, "Looks like we'll have to replace the rear end just like I had to on my Titan." (her & her husband have a Titan identical to mine). Further discussion with her revealed that the second rear end that they got for her truck was bad right out of the crate. And for you naysayers, her husband is a mechanic at the dealership. She also told me that they have replaced rear ends in over 10 trucks. I didn't ask how many of those 10 have had rear end troubles again.
It took almost three weeks for my rear end to be replaced, but the dealership was great and gave me a loaded out Altima 3.5 to drive. I've got approx. 6K miles on my new rear end and have towed my boat only once. So far, so good. We'll see.
There is a problem with Titan rear ends - period. No urban legend. No trolling/baiting/whatever. Why no TSB you ask? Uh, well hello....you gotta know what the fix is before you can issue a TSB. Nissan doesn't know what the fix is. That's why they are R&R'ing rear ends with virtually no questions asked. And the fact that rear end assemblies are incredibly backordered should tell you something too.
What concerns me is that being a mechanical engineer, I know what my design limits are and what my safety factors are. So if Dana Corp. knew that Nissan intended to rate their trucks at 9500lbs, Dana's rear end design should be capable of at least 10,500lbs before catastrophic failure. That's basic design engineering. It speaks a lot when I see a finned aluminum cover on a differential that is unchanged. First, you don't implement a component like this because it looks cool (no pun intended) due to the incremental cost to the product. And believe me, the Japanese are incredibly sensitive to anything that drives up the cost of the product. Second, there's only one reason for adding fins in an application such as this - there's an issue with heat build up and dissipation. IMHO, someone dropped the ball design-wise. But hey what do I know? I'm just a 49 year old engineer who basically baby's his truck.
Lastly...I'll include this info for jimb:
Christina Adams - service writer, Dan Vaden Nissan, 912-920-5481
Call her and verify if any of what I said or the work they did to Tom Adams' truck (mine) or hers or anyone elses' is "urban lengend". You've been so condescending and pompus in this thread that it would be a pleasure to shove this up your you-know-what. Nevermind....even if you did find out all this was true, you wouldn't have the balls to apologize.
Tom
